Which check is performed after maintenance on a landing gear component?

The drop check is performed after maintenance on a landing gear component to ensure that the system operates correctly and safely. This check involves verifying the operation of the landing gear mechanism by allowing the gear to drop and then retract. It assesses whether the components function as intended under the conditions they will face during operation. The drop check specifically focuses on the performance and reliability of the landing gear after maintenance has been completed, making it an essential part of post-maintenance procedures.

Other checks, like routine inspections or functional tests, serve different purposes. Routine inspections are more general and are conducted regularly to ensure overall aircraft safety, while functional tests may address various aircraft systems but are not as specific to the landing gear drop mechanism. An alignment check is critical for ensuring that the landing gear is correctly aligned for optimal performance but does not specifically indicate that the gear drops and retracts correctly after maintenance.
